To all whom it may concern.-

Be it known that I, Sander. V. Wssxs, a citizen of .theUnited States, residing at Highland Park, in the county of Hamilton and State of Tennessee, have invented a 'newand useful Reversible-Disk Plow, of

which the following is a specification.

My present invention relates to a reversible plow of wheeled frame carrying instance, a disk, reveron'qne side only of the land without turning the plow. In plows of this type the disk is ordinarily mounted on a atandard 'which is oscillated to swing the disk horizontallyto-opposito angular positions with to the line of draft. This character of reversal is open to -"thc objectiontlmt the disk, is turned while in the und,

'unless the entire plow frame is first elevated an the then reversed after being lifted out of e soil.

Furthermore, it is impomible,:except by the evation' My even, this cumbemme clearance by the disk is impossible, because the eleof the entireplow frame to lift the disk out of the ground for the purpose of clearing an obstructionwhich maybe located in the line of the furrow, and u the obstruction projects materially above the surface of the method of causing its vation of the plow frame is insufficient in exterf. for this purpose. Another objection to this type of plow is that in order to maintain the same relation between the furrow wheels and the disk, in both positions of the latter, said disk must be mounted midway between the wheels as it would otherwise be located nearer the .fro'irt furrow whcel while plowing in one direction and the res; furrow wheel when plowing in the opposite direction, immediately in advance of the rear furrow wheel regardless of the direction in which the plow is moving.

Having in mind these commonly acknowledged in efficiencies of an otherwise highly efficient type of plow, one object of my invention is to produce a plow equipped with. a' disk so mounted that its reversal will'causo the withdrawal of the disk from the ground and-its re-prcsentation to the ground in reverse position, as distinguished from the twisting or turning of the disk in the ground in the ordinary manner.

Another object is to so mount the disk that the latter Will' be.sl1ift0d .in the act of reversal from a positidn adjacent to one furrow wheel to ujsimilar position adjacent to the other furrow wheel, so'that, instead of being located as usual at the same intermediate point between the wheels at all times, the disk, whether moving in-onedirection onthe other, will be located io nediatoly in advance of the rear furrow wheel. I,

Another object of the invention is to reverse the disk on a horizontal axis in such a manner that the disk whereas the natural position of'the disk is v will be withdrawn edgewise from the ground while the disk is being turned with its concave side moving toward the ground so that the disk will be withdrawn from the ground without scraping upthe latter as would be thecase if the disk was swung in the opposite direction.

A further object of the invention operated by the draft appliance, versing the disk on a horizontal axis when the position of the draft appliance with respect to the plow is changed at the end of the furrow.

A further object of the invention is to provide automaticmeans whereby the disk will be locked in each of its positions, and a still further object of the invention is to provide means operated by the draft appliance to shift the furrow wheels laterally in opposite directions, whereby the front furrow wheel will be located in the line of the lastfurrow, while the rearfurrow wheel will be located in the line of the. new furrow,oach of the wheels serving alternately as a front and a rear furrow wheel.

is to provide means,

Several other objects subordinate to those stated will appear'as the succeeding description of the illustrated embodiment of the invention is developed In the accompanying drawings- Figure 1 is a plan view ofmy plow when in position for moveinent to the left. Fig. 2 is a similar view of the plow when in position for movement in the reverse direction or to the right. Fig. 3 is a side elevation of the plow viewed from the unplowed land. Fig. is an enlarged longitudinal section through the mam frame and the immediately associated parts. Fig. 5 has transverse section on the line'5-5 of Fig. 4. Fig. 6 is an enlarged plan view of the main frame and a portion of the reversing shaft and sleeve, certain. of the parts being broken away to facilitate illustration. Fig. 7 is a detail section on the line 7-7 of Fig.- 6. Fig. 8 is a detail view of the reyersing bar, and Fig 9 is a diagrammatic view illustrating the reversal of the disk.

Each part is indicated by the same numeral in the several views.

The frame structure of the plow includes a center casting or main frame 1, and two wheel frames 2 and 3 of angular form, as shown in Fig. 1, supported attheir outer ends by furrow wheels 4 and 5. The inner ends of the wheel frames 2 and 3 are disposed transyerse to the plow and are slidably received within guide boxes 6 at the opposite ends of the main frame 1 and preferably integral therewith. Those portions of the wheel frames which are received within the guide boxes are of square or other angular form in cross section in order to prevent relative movement .of said frames with respect to the main frame, except in a direction transverse to the plow.

for automatically re-' To provide for the vertical adjustment of the frame structure relative to the wheels, and to provide further for the shifting of the furrow wheels to enable the plow to be guided, the wheels are mounted on crank axles 7, as shown in Figs. 1 and 3. Each'of these axles includes a standard 8 which is angular in cross section and is passed througha sleeve 9 rotatttble'in a vertically disposed bearing 10 at the outer-end of one of the wheel frames. Each sleeve 9 and the wheel frame in which it is mounted, is designed to slide vertically upon the adjacent standard 8 as the frame structure is raised or lowered by the manipulation of the frame adjusting levets 11. Each of the levers 11 is fulcrumed intermediate of its ends'upon a toothed segment l2and is connected at its inner end bya link 13 to the adjacent wheel frame. Thelsegment 12 is swiveled at the upper end of the standard 8 and is designed to be retained by a latch 14 carried'by the lever. It will thus be seen that the lovers may be released from the segments and adjusted to raise or lower the frame structure of the plow and then re secured by the cooperation of the latches and segments to maintain the plowframeat the elevation to which it has been adjusted.

In order to permit the crank axles to be swung for the purpose of shifting the furrow wheels in the manner necessary to steer the plow, particularly when transporting the latter from one point of use to another, the sleeves 9 are.provided with arms 15 connected to a steering lever 16, atbpposite sides of the fulcrum of the latter, by steering rods 17. The steering lever 16 is fulcrumed on a, toothed segment 18, swiveled upon itssupport in a manner to be hereafter escribed, to accommodate the different angular positions assumed by the steering'rod 17 and cooperating with a latch l9 or. the lever 16. By the manipulation of the lever 16, the crank axles at the opposite ends of the plow, normally retained in parallel relation for straight away plowing, may be moved in opposite directions for the purpose of causing the furrow wheels to assume opposite anguliir positions to enable the plow to be steered around a corner, either to the right or left, in plowing around four sides of afield, or iii transporting the plow from one 4 field toanothen,

The manner of mounting the disk will be best understood by a consideration of Figs. 4 to 7. Midway of the ends of the central castingor main frame 1, the latter is provided with a socket 20 in which is mounted the hub 21 of the disk reversing sleeve 22, the upper edge of the hubtbeing flush with the'upper surface of the central portion of the frame. The hub 21 is rotatable on a vertieal axis to shift thesleeve 22 which extends in opposite directions from the hub, see Figs. 1 and 6, the hub being 1 provided with vertically disposed trunnions 23- and 24,

one of which is journaled inthe bottom wall of the socket 20 and the other of which passes through and is journaled in the cap-plate 25 retained upon the upper surface of the frame 1,- as for instance, by bolts 26. Since this cap-plate 25 has now been located, attention may be directed to the fact that the support upon which the segment 18 is swiveled, as heretofore stated, is an arm .27 extended laterally from the cap-plate 25, as sliown in Fig. 6.

Rotatable in the sleeve 22 and extended beyond the ends thereof, is what may be termed the disk reversing shaft 28 provided adjacent to one end, to-wit, the end box 29 for the reception of the spindle 30 of' the furrow posed normally at an angle tqthe line of draft, since the disk, whose axis is at right angles to the shaft, must be disposed t such an angle. The axis of the journal box 29 is not normally disposed horizontally, but is inclined sufficiently to provide for the required backward tilt of the disk. At the dxtrcmity of the reversing shaft, beyond the box 29, are located a pair of cars 32 between scraper 34 retained by the shank in operative proximity to the front face of the disk 31. It will now be understood that by swinging the reversing sleeve 22 from the trunuions 23 and 24 as, an axis, the disk may be shifted from its angular position adjacent to one end of the plow, as shown in Fig. 1, to an opposite angular position adjacent to the opposite end of the plow, as shown in Fig. 2. It will be equally obvious that by rotating the reversing shaft 28, the disk may be reversed upon a horizontal axis intersecting the axis of the disk so that the latter will not only be shifted to an opposite an'gularposition adjacent to the opposite end of the plow, but will" also becauscd to face in the opposite direction.

reversing bar 35 spaced from the cap-plate 25 by a boss 36. At one cud of this bar is secured the spring-37 of the drivers seat 38, and to the opposite end of the bar is so cured, by suitable means, a draw-bar or other suitable draft appliance'39 by means of which the draft animals are hitched to the plow. At the opposite ends of the main frame 1 said frame is provided with apertured =keeper flanges 40 located above the guide boxes, and irieach of its reversed positions, the reversing bar 35 is located under one of these flanges and in line with the framel, see Figs. 1 and'2. To retain the reversing bar in either position, the latter is equipped with a locking pin 41 which passes through coincident apertures in'tlie reversing bar and the adjacentkeeper flange and also through an apertured lug 42 integral with the bar and overlying the keeper flange, as shown in Fig. 4; The upper end of the locking pin 4l'has a slot and pin connection with one end of a foot lever 43, urged in one direction by a spring 44 and designed to be swung in the 'opposite direction by the foot of the operator to withdraw. the pin .41 from its locking position, When the reversing bar is unlocked'or released, it" rn'a y be swung around, as for instance, from the position indicatedjiu, Fig. 1 to that indicated in Fig. 2, whenthe plow reaches one end of the furrow 'and the draft animslsare driven around to the opposite end of the plow, 'priparatory to drawing the same back across the field.

The act of reversing the position of the reversing bar 35 automatically effects the shifting -of the disk from oneend of the plow to the other and also-the reversal of the disk upon a horizontal axis, as heretofore explained. To accomplish these results, the reversing bar 35 is provided with a pair of laterally extending arms 45 and 46 disposed radially, as shown in Fig. l, with respect to the axis of thebar. The arms 45 and 46 are provided with pendent lugs 47 and 48 whose active faces are disposed radially to the axis of the arm and, approximately at right angles to each other. The

lugs 47 and 48 are designed to alternately engage a lug which is retained the end of the curved shank 33 of a which pro ects toward the plowed land, with a journal opener or disk 31. The reversing shaft 28 occupies at all times a substantially horizontal position, but is dis- Journalcd on the upper trunnion 24 of the hub 21 is a 'terval. If now, the reversing bar bar, the engagement effected between I be swung from the position shown from its angular position adjacent to 50 extended upwardly from the reversing sleeve 22 at the end thereof opposite the disk. Thus in Fig. l, the ing 47 on the reversing bar is shown in contact with the lug 50 on the reversing sleeve, while the lug 48 is shown removed from the lug 50 by a considcmble inis swung around, the lug 47 will recede froni the lug 50, while the lug 48 will approach the lug 50 and finally contact therewith, after the reversing bar has made a quarter turn. During the subsequent movement it and the sleeve by the engagement of the lugs will cause said sleeve to in Fig. l to that shifting the disk the wheel 5 to an opposite angular position adjacent to the wheel 4, which latter, having served as the front wheel of the plow, will now become the rear wheel, as the plow is drawn back across the field in the opposite direction. This swinging of the reversing sleeve to transport the disk is also utilized to rotate the disk reversing shaft 28 for the purpose of withdrawing the disk from the ground and representing the latter to the ground in reversed position. To accomplish this, the shaft 28 is provided upon its extremity with a gear wheel 51 shown.i n Fig. 2, for the purpose of contacting with the under side of the segmental track 52 extending from and preferably formed integral with the central casting or main franre 1, sec Figs. 5 and 6. As the reversing shaft 28 swings laterally with the rever'sing sleeve 6 which is swung around by the reversing bar in the manner described, the engagement between the friction wheel and the under side of the track 52 will cause the reversing shaft to rotate, thus revelling the disk so that, by the time said disk has been shifted, from one location to the other, it will also be reversed and will be presented to the grouno in reverscd position. For the purpose of aecurately limiting the movement of the reversing shaft, in order to insure the accurate reversal of the disk, said shaft is provided adjacent to the friction wheel or .pinion 51 with a combined stop and locking lug 53 which, when the reversing shaft has rotated sufficiently, will contactwitlr a stop flange projecting from the main frame-l, as shown in Figs. 6 and T. This engagement of the flangeirnd lug takes place a short time before the swinging movement of the. reversing sleeve and shaft is completed. Therefore, while tho rotary movement of the shaft w ill' 'ljc arrested, thr laltcr will, nevertheless, continue to move laterally with the pinion 51 sliding along the track 52 until the end of the lug 53 finally engages the horizontal recess 55 at the inner end of the flange 54. The cngagerrrcnt of the lug 53 with the walls of the recess 55 will positively lock the reversing shaft against rotation so as to preelude he possibility of accidental reversal of the disk by an strain sustained thereby. It will, of course, he uniiersto xl that the flange 54 and the recess 55 are 'duplic'atod at each end of the track 52, see Fig. 6, so that the reversing shaft is arrested and locked at each limit of its movement.

Inordcr to rigidly hold the reversing sleeve 22 in each of its opposite angular positions, the opposite walls of the socket 20 are of angular form, as shown in Fig.0, to provide ang'ularly related abutments 56 against which the sleeve is held firmly by the engageof the reversing merit of one of the lugs 47 or 48 with the lug 50. It will be noted, however, by reference to Figs. 1 and \J. in which the parts appear in corresponding ursilions, that the strain imposed upon the sleeve while plowing is rcsisrcd by the solid abutnrents of the main frame and not by tho lugs. At this point attention is particularly din-cred to the fact that in reversing the disk. rho latter is turned in a direction which will present the concave side of the disk opposite the ground when the disk reaches an intermediate position, as shown diagrar 'matically in Fig. 9. The turning of thc disk in this direction enables it to' be withdrawn from the ground with the utmost freedom, instead of being' impeded by the soil, as would be the (use ifthe reversing shaft were turned in the opposite direction, which would obviously cause the lower edgiof the concave side of the disk to be raised against the resistance of the soil in a mann r similar to the lifting of a shovclful of dirt. Furthermore, the freedom with which the disk is reversed is greatly facilitated by reason of th fact that the reversing shaft'is moving laterally while the disk is being rcvcrscd, since it will be seen that th formcr rnovcrncnoservcs to tilt the disk forwardly, whilc its lowercdge is being elevated, so that tho l0\\'t-l ((lgc of the disk, instead of being dragged back through the ground, is lifted out of the ground without. malt-rial resistance.

Another prominent feature of novelty HFidca in thrautomatic shifting of the furrow wheels 4 and 5 in a latcral direction with respect to the plow. In plows of this type the front furrow whet-l should be located in the line of the last furr ow turned, while the rear furrow Whccl should be located in the line of the new furrow, see Fig. 1. Thus the rear furrow wheel should be located in a new furrow and inrnrcdialrly in rwrr of thrdisk, while the front furrow wheel should bc a considerable distance in advance of the disk and offset latr rally from'the plow frame a sufficient distancc'to present it in the furrow last made. If this relation of the wheels and disk 'is established it will be seen that when the plow is reversed, the wheels will not occupy their proper positions. I- have therefore providr d means whereby the turning of the reversing bar by the draft animals will nobonly move the disk to thc oppositc end of the plow and reverse the same, butwill also effect relative shifting of the plow frame and furrow wheels so that the latter will occupy the proper rela- (ion to the disk and frame when the plow is traveling in the reverse direction.

We have al'ready seen that the inner parallel ends of the front and rear wheel frames 2 and 3 are disposvd transversely of the plow and are slidably received wit hin the guide boxes 6. It, will now be seen, by reference to Fig. 1, that the frames 2 and 3 are provided at. their inner ends with cars 57 and 58 connected respectively to the outer ends of the arms 45 and 46 by bent links 59 and 60. These links arelocated in the plane. ofthe space between the cap-plate 25and the rcvcrsing bar 35, see Fig. 4, sotlrst when the reversing bar is turned to one position or the other, the links may pass freely between these elements of the structurc. ((ompare Figs. 1 and 2.) It will thus be seen that when the plow reaches the end of a furrow and the draft animals are driven from one end of the plow to the other, the main frame and the wheel frames "will be caused to sincc,'as a matter of fact, the reversal of the plow, or-' ganiz'cd as shown in Fig. 1, may effect the lateral shifting of the-main frame on the wheel frame 3 and the shifting of the wheel frame 2 both with the main frame and relative thereto, so that-the wheel 5 will remain 4i the furrow just made while the wheel 4 will occupy a.

plane. interme'diate'oi the'main frame and the wheel 5 to dispose it in the line of the furrow to be made, as the plow is now drawn back across the field in the opposite direction with the parts organized as shown in Fig. 2. The land sidowheel 61 is mounted in a bracket -62 swiveled at the'outer end of an arm 63 extending iateraliy from the main frame of the plow and. preferably, though not necessarily, formed integral with the track 52.

In certain of the claims, I have employed the term double ended plow", which term is intended to define a plow of that type which is movable back and forth across a field without turning, eitherend of the plow frame' occupying an advanced position, according to the direction in which the plow is moved.

In certain broad aspects, the construction illus-- tinted herein involves the invention described and claimed in the copending application of Charles M.

Malloryand .lames M. Slatighfer', Serial Number 319, 318, but it is to be understood that I make no claim to any structure disclosed in the said Mallory and Slaughter "applichtion.

It is thought that the construction and operation of the.

plow will be clearly understood from the foregoing description, but it is'obvious that many structural changes, modifications, or variations -may be effected without departing from the spirit of the invention, and I therefore reserve-the.riglit'to change ormodify the illustrated construction within the scope of-the protection prayed. v
